UEFN Crashing On Project Load

UEFN is crashing when launching a specific project. I can open other projects fine, and my team members can open the project fine, it’s just me that is crashing.

I can see when I click to load the project, it gets to the map initialization step right before crashing. Looking through the log for errors, I am seeing primarily that the LOGHotfixManager is onlly able to successfully patch 146 assets of the 147 it tried.

Specifically it fails here: [2023.09.21-13.40.26:360][487]LogHotfixManager: Error: [Item: 80] /Game/Items/Datatables/AthenaLootPackages_Client.AthenaLootPackages_Client: The new value 0.25" is not a number when it should be.

I’m not sure if this is THE ISSUE, but it’s the one that stands out to me. Any advice here?

I have tried verifying my UEFN, updated my NVIDIA drivers, turned off MSAA. I can’t seem to find this file it’s having a hard time parsing, I’m not sure if it lives in some pak file or something.

EDIT:
The actual crash log is as follows:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

I’m noticing that the link you provided to get your reference Id, requires that I can open the project in editor to click the report button, however, I can’t get to this point :frowning: Looking at my crash directory, I can’t seem to find a reference ID, but maybe one of these xml tags is the reference id? Such as one of these?
